Study Description

Brief Summary:

The purpose of this study is to evaluate an investigational treatment for interstitial cystitis. Interstitial cystitis is a chronic bladder disease that includes the following symptoms: Urinary frequency during the day,urinary frequency at night, urinary urgency and bladder discomfort relieved by voiding.

Presently, there is no cure for interstitial cystitis. The response to current treatments is poor. Patients with interstitial cystitis have a poorer quality of life. The cause of interstitial cystitis is unknown. This study is evaluating the drug Humira® (adalimumab) for improving the symptoms of patients with interstitial cystitis. Humira® is an injectable anti-inflammatory medication that has been available for use since December 31, 2002. Humira® has been FDA approved for the treatment of rheumatoid arthritis, psoriasis, ankylosing spondylitis, and Crohn's disease. These diseases have similar characteristics to interstitial cystitis. This study will evaluate an investigational use of Humira® for the treatment of interstitial cystitis.

Detailed Description:

Interstitial cystitis (IC) is a chronic disabling bladder syndrome characterized by urinary frequency, nocturia, urinary urgency, and pain with bladder filling-relieved by emptying. There is no cure for IC and the treatment options are suboptimal. Patients with IC report significant negative effects on their physical and mental quality of life. The etiology of IC is unknown. Certain aspects of IC suggest that autoimmunity may play a role in initiating or sustaining the chronic inflammatory response. Bladder biopsies of patients with IC demonstrate an increase number of mast cells. Mast cell activation with the release of tumor necrosis factor (TNF) may mediate this bladder inflammation. Humira® (adalimumab) is a medication that blocks the effect of TNF. Humira® (adalimumab) is FDA approved for the treatment of rheumatoid arthritis, psoriasis, ankylosing spondylitis, and Crohn's disease. These diseases are similar to IC. In this study, the hypothesis being tested is that Humira® (adalimumab) will show efficacy at reducing the symptoms of IC.

Secondary Outcome Measures :

1. Interstitial Cystitis Symptom Index (ICSI) [ Time Frame: Baseline/ 12 weeks ]
   Improvement in O'Leary Sant Interstitial Cystitis Symptom Index (ICSI) Total scores on a range scale: 0-20 (0, meaning no symptoms, to 20, meaning the most severe symptoms)
2. Interstitial Cystitis Problem Index (ICPI) [ Time Frame: Baseline/12 Weeks ]
   Improvement in O'Leary Sant Interstitial Cystitis Problem Index (ICPI) Total scores on a scale: 0-16 (0, meaning no symptoms, to 16, meaning the most severe symptoms)
3. Pelvic Pain Urgency/Frequency (PUF) Score [ Time Frame: Baseline12 Weeks ]
   Pelvic Pain, Urgency/Frequency Symptom Scale Total scores on a scale range: 0-35 (0, meaning no symptoms, to 35, meaning the most severe symptoms)
4. Global Response Assessment (GRA) [ Time Frame: Measured at12 Weeks ]

   Percent(%) of patients who reported 50% or greater overall improvement in their condition.

   Score on a scale range (improvement 0%-100%)
